If HissGate and BuzzGate are everywhere, is your iPhone 7 really making a strange sound?


What’s going on with iPhone 7 hisses and buzzes? We’re investigating!

Yesterday, it was iPhone 7 Home buttons and capacitive gloves, today it’s iPhone 7 making a “hiss” or “buzz” sound. Every year, the tidal wave that is iPhone launch attention sweeps up all sorts of “gates” in its wake, and it can be difficult and confusing to sort the real from the imagined.

So, we decided to test our iPhones 7 and heard the sound as well. Then we tested our iPhones 6s and also heard it. And our iPads Pro. And AirPort Extremes. And… you get the idea.

iPhone 7 Plus, at least to my ear, was louder and varied more than any of the other devices, but they all made the sound. Based on teardowns, it seems to come from where the radios are, specifically the Wi-Fi radios. That makes sense, given that most people are noticing the sound when their iPhones are restoring and under heavy load.

Since several of us, as well as numerous people in the iMore community and on Twitter, report hearing similar sounds from multiple different types of devices as well, it’s very possible this is nothing out of the ordinary. Perhaps people are only noticing it now because it’s new iOS and iPhone week, and they’re rightfully extra-vigilant and attentive following the Galaxy Note 7 recall.

It’s also possible there’s something new and different going on. So, we’re going to looking into it and will update with anything else we find.

In the meantime, let me know if you noticed any unusual sounds from your new iPhone 7, and whether or not you hear anything similar from your older iPhones and other devices.
